Aims: To evaluate the utility of endoscopic obliterative therapy with n-butyl-2-cyanoacrylate (tissue adhesives) for gastrointestinal varices and to investigate the incidence of serious complications. Methods: Endoscopic obliterative therapy with n-butyl-2-cyanoacrylate was performed on 228 gastrointestinal variceal patients; 221 gastric varices, 5 duodenal varices, and 2 anastomotic varices af...

In our previous study, the healing effect of proton pump inhibitor plus rebamipide for endoscopic submucosal dissection-related artificial ulcer smaller than 40 mm showed statistical significance. However, such effect of the combination was not yet clear for ulcers with dissected diameter more than 40 mm. The aim of this present study was to resolve this problem under sufficient statistical pow...

OBJECTIVES The impact of preoperative endoscopic therapy on the difficulty of laparoscopic Heller myotomy and the impact of the difficulty of the myotomy on long-term outcome has not been determined. This study was undertaken to determine whether preoperative therapy impacts the difficulty of laparoscopic Heller myotomy and whether preoperative therapy or difficulty of myotomy impacts long-term...

the use of anticoagulant and antiplatelet agents has become more prevalent during the past decades. these drugs may potentially cause gastrointestinal (gi) bleeding. thus, there is an increasing need for gi endoscopy in patients who take these medications. in patients who take anticoagulant and antiplatelet agents, the appropriate conditions under which endoscopic procedures should be performed...

A 61-year-old male on anticoagulant therapy underwent an endoscopic multiple colon polypectomy in our Department according to established procedures. Several days later he developed an intramural colonic hematoma, which burst into the peritoneal cavity leading to fatal intra-peritoneal hemorrhage. Herein we present the case and discuss the causative role of the anticoagulant therapy but also of...

juvenile nasopharyngeal angiofibroma (jna) is a rare, benign and locally invasive tumor. massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. in this article, we r...
